The twisted jets and magnetic fields of the extended radio galaxy 4C 70.19
M. Weżgowiec, M. Jamrozy, K. T. Chyży +4
The appearance of the jets and lobes of some radio galaxies makes it difficult to assign them to a known class of objects. This is often due to the activity of the central engine a…

The Perseus cluster is the brightest X-ray cluster in the sky and is known as a cool-core galaxy cluster. Being a very nearby cluster, it has been extensively studied. This has pro…
Core prominence as a signature of restarted jet activity in the LOFAR radio-galaxy population
Dhanya G. Nair, Raffaella Morganti, Marisa Brienza +6
(abridged) Characterizing duty cycles of recurrent phases of dormancy and activity in supermassive black holes in active galactic nuclei is crucial in understanding impact of energ…
A Deep Dive into the NGC 741 Galaxy Group: Insights into a Spectacular Head-Tail Radio Galaxy from VLA, MeerKAT, uGMRT and LOFAR

We present deep, wideband multifrequency radio observations (144 MHz8 GHz) of the remarkable galaxy group NGC 741, which yield crucial insights into the interaction between the…
New supernova remnant candidates in the LOFAR Two Metre Sky Survey
K. Tsalapatas, M. Arias, T. Shimwell +3
In spite of their key role in galaxy evolution and several decades of observational efforts, the census of supernova remnants (SNRs) in our Galaxy remains incomplete. Theoretical p…
Sporadic radio pulses from a white dwarf binary at the orbital period
I. de Ruiter, K. M. Rajwade, C. G. Bassa +14
Recent observations have revealed rare, previously unknown flashes of cosmic radio waves lasting from milliseconds to minutes, and with periodicity of minutes to an hour. These tra…
Into the depths: Unveiling ELAIS-N1 with LOFAR's deepest sub-arcsecond wide-field images
